Electric and flanged power station gate valve

Uses

Vacuum gate valve is welding and drive mode is electric. The valves are suitable for working temperature 425 ℃ and 550 ℃ or less, or less for water, steam or air as the working medium of piping, as the opening and closing device; Particularly suitable for power plant turbine condenser and vacuum negative pressure system, the vacuum insulated sealing function.

Structural characteristics of

1, vacuum sealing structure, design and packing room, make the system from the atmosphere, with good environmental performance.

2, well-selected materials, the national standards, the materials of high quality in an all-round way.

3, seal pair of advanced and reasonable, improve the sealing performance, long service life.

4, open-close part adopts parallel disc two-way elastic seal, friction small, opening and closing easy, convenient maintenance, reliable sealing, good performance.

5, the valve stem surface is adapted to nitriding treatment and conditioning,so that it have good corrosion resistance, abrasion resistance and abrasion resistance.

6, flange gasket adopts composite materials, because of large expansion coefficient and good airtight performance, than it can reliable guarantee system from the atmosphere.
